Description

Technical Field

[0001] The invention belongs to the technical field of food, and relates to functional coffee containing a Chinese medicinal extract which is both medicinal and edible, and a preparation method thereof. Background Art

[0002] Coffee is a popular drink. The main ingredient of coffee is caffeine, which is a natural alkaloid that can stimulate the central nervous system, refresh the mind, aid digestion, promote diuresis, and quench thirst. It also has strong antioxidant, smooth muscle relaxation, heart strengthening, liver protection, fat elimination, appetite stimulation, and dehumidification effects. A moderate amount of caffeine can reduce muscle fatigue and promote the secretion of digestive juices. In addition to caffeine, coffee also contains organic acids such as chlorogenic acid and tannic acid. Chlorogenic acid has multiple physiological functions such as antioxidant and anti-inflammatory; tannic acid can make coffee have an astringent taste. Drinking coffee in moderation helps promote metabolism and has certain benefits for human health.
